ncpfs: fix a braino in OOM handling in ncp_fill_cache()

2016-03-16T15:42:59+00:00

commit 803c00123a8012b3a283c0530910653973ef6d8f upstream.

Failing to allocate an inode for child means that cache for *parent* is
incompletely populated.  So it's parent directory inode ('dir') that
needs NCPI_DIR_CACHE flag removed, *not* the child inode ('inode', which
is what we'd failed to allocate in the first place).

ncpfs: don't allow negative timeouts

2015-11-21T00:17:32+00:00

This code causes a static checker warning because it's a user controlled
variable where we cap the upper bound but not the lower bound.  Let's
return an -EINVAL for negative timeouts.

fs/ncpfs/dir.c: remove unnecessary new_valid_dev() check

2015-11-09T23:11:24+00:00

new_valid_dev() always returns 1, so the !new_valid_dev() check is not
needed.  Remove it.

fs: Drop unlikely before IS_ERR(_OR_NULL)

2015-09-29T13:13:58+00:00

IS_ERR(_OR_NULL) already contain an 'unlikely' compiler flag and there
is no need to do that again from its callers. Drop it.

switch generic_write_checks() to iocb and iter

2015-04-12T02:30:21+00:00

... returning -E... upon error and amount of data left in iter after
(possible) truncation upon success.  Note, that normal case gives
a non-zero (positive) return value, so any tests for != 0 _must_ be
updated.

make new_sync_{read,write}() static

2015-04-12T02:29:40+00:00

All places outside of core VFS that checked ->read and ->write for being NULL or
called the methods directly are gone now, so NULL {read,write} with non-NULL
{read,write}_iter will do the right thing in all cases.
